    • Small but mighty speaker!
Color: Pink
The Ultimate Ears WONDERBOOM is such a great little speaker! I was impressed right out of the box. The sound quality is amazing for something so compact—rich, clear, and with surprisingly powerful bass. The 360-degree sound really fills the space, whether I’m indoors or outside. It’s also super durable and waterproof, which makes it perfect for the pool, the beach, or just hanging out in the backyard. I’ve even dropped it a couple of times, and it’s held up without a scratch. The battery life is solid, lasting through long playlists and hours of use. What I love most is how portable it is—it’s lightweight and easy to toss in a bag for trips or adventures. Plus, the pink color is so fun and stylish! If you’re looking for a speaker that’s compact, reliable, and sounds fantastic, I can’t recommend this one enough. ... show more

It’s soooo cuteee 🥹 and my fav color too. People tryna steal it from me lol. This boom box was definitely worth it. It’s a travel size(fits perfectly in my hands), very loud (bass is really nice) and it looks exactly as shown in the photo. It was hard for me to decide how to turn it on but YouTube was helpful. The quality is top notch, it’s very strong. Fell a few times and it was nothing! Material it’s made from is just perfect (giving sturdy rubber-typed) I haven’t tested the water proof theory as yet tho but will update once I do. It connects and work well. However, I had issues connecting to a new device after pairing with another before and had to reset the box in order for it to pair with another device (YouTube helped with that too). After using it more, it doesn’t seem to have any issues pairing with new devices, hope it continues. I hope that helped! ... show more

    • Hands down the best portable speaker
Color: Black
I have had a wonderboom 2 for years and used and abused it. I finally bought the new wonderboom 4 for one main reason. The wonderboom 4 finally has usb-c charging which now all of my family's electronics are on usb-c. I bought two of these so that they can be paired together for a larger sound experience. These things are waterproof, durable and amazing sound quality from directions. The battery life last forever it seems like with these speakers. Prefect size to be portable with big sound. ... show more

    • Woooow
Color: Black
I think I came across this through a review. And wow, I’m glad I purchased this over the JBL Flip 6 that I was planning on purchasing. They were relatively the same price range. Bought this on a sale. This is a small form factor, and so far it’s been durable. I’ve brought it into the pool before as well and no issues. It’s definitely portable, just grab a carabiner and it’ll go anywhere. Although it does slightly have weight. I’d say, battery is fair. The outdoor mode definitely makes it louder. I’d buy again so that I can connect them together! ... show more

    • Sounds good for the sale price but on/off sound is annoying
Color: Black
Sounds good for a small speaker for the sale price. Pairing and controls are easy. Unfortunately, it has an annoying set of tones played every time you turn it on and off that cannot be disabled.

    • Amazing little speaker for the money

I browsed various online forums and UE’s products seem to be top of a lot of people’s recommendations for affordable portable speakers. The wonderboom in particular. I got the 4 instead of the 3 mainly because it has USB-C charging port instead of Micro USB. Solid battery life (10-12 hours of playback from my experience, longer on lower volume and changing listening modes), easy volume control with big buttons, amazing sound from such a compact size, and solid build quality. I’ve taken this camping a couple of times and dropped it from a picnic table onto hard gravel and brushed it off, still worked the same. Kinda wanna buy a second at some point to sync them. ... show more

    • Powerful Sound in a Compact Package
Color: Black
I couldn't be happier with my Ultimate Ears WONDERBOOM Bluetooth Speakers. The set of four speakers delivers robust, immersive sound with deep bass and impressive 360-degree audio that fills any room or outdoor space. One of the standout features of these speakers is their portability. They're lightweight, easy to carry, and, best of all, waterproof and dustproof. Whether I'm at the pool, the beach, or just at home, I know these speakers can handle it all. The fact that they float is an unexpected but fantastic bonus! The 131-foot range is another major plus. I’ve wandered all over my house and yard without losing connection, and the battery life is equally impressive, offering hours of uninterrupted playtime. The sleek black color looks stylish and modern. Overall, these speakers are a fantastic investment for anyone who loves high-quality, portable sound. Highly recommend! ... show more
